Bromobenzene　is　a　kind　of　widely-used　chemical　raw　material.　This　thesis　studies　its　effects　of　degradation　and　debromination　under　the　electron　beam　irradiation.　And　its　radiation　degradation　characteristics　are　studied　through　comparing　the　changes　of　the　bromobenzene　concentration　in　the　bromobenzene　solution　before　and　after　being　irradiated,　in　the　terms　of　different　solvent　systems,　pH　conditions　and　initial　concentration.　Meanwhile,　the　changes　of　the　bromide　ion　concentration　in　the　solution,　before　and　after　being　irradiated,　are　also　studied.　The　results　show　that　the　practice　of　using　radiation　technology　to　treat　bromobenzene　wastewater　is　a　workable　plan.
